public final Class NoopOptimizer

extends AbstractOptimizer
Class Inheritance
Imports
java.io.Serializable, org.hibernate.id.IntegralDataTypeHolder
An optimizer that performs no optimization. The database is hit for every request. Using this implementation is probably not the most efficient choice.

Doc from org.hibernate.id.enhanced.Optimizer.applyIncrementSizeToSourceValues.

Are increments to be applied to the values stored in the underlying value source?

Returns:boolean

True if the values in the source are to be incremented according to the defined increment size; false otherwise, in which case the increment is totally an in memory construct.

public Serializable generate(AccessCallback callback)

Implements org.hibernate.id.enhanced.Optimizer.generate.

Doc from org.hibernate.id.enhanced.Optimizer.generate.

Generate an identifier value accounting for this specific optimization. All known implementors are synchronized. Consider carefully if a new implementation could drop this requirement.

Parameters
callback:AccessCallback

Callback to access the underlying value source.

Returns:Serializable

The generated identifier value.

public IntegralDataTypeHolder getLastSourceValue()

Implements org.hibernate.id.enhanced.Optimizer.getLastSourceValue.

Doc from org.hibernate.id.enhanced.Optimizer.getLastSourceValue.

A common means to access the last value obtained from the underlying source. This is intended for testing purposes, since accessing the underlying database source directly is much more difficult.

Returns:IntegralDataTypeHolder

The last value we obtained from the underlying source; null indicates we have not yet consulted with the source.
